KVM failover to another KVM server

Well when I try to use the create command I get this:

virsh # create /etc/libvirt/qemu/ubuntuTest.xml
error: Failed to create domain from /etc/libvirt/qemu/ubuntuTest.xml
error: unknown OS type hvm

and I'm using virt-install by using the below command:
self.runCommand("virt-install --hvm --name " + name + " --ram " + ram + " --file " + filename + " --file-size " + hardDriveSize + " --network bridge:br0 --cdrom " + cdrom + " --accelerate --noautoconsole --vnc")

I'm not sure if there is some where everyone keep scripts they write but for now I'm putting them on my Wiki here:
They are not the best scripts but they are are written in python and it calls os.system(command) to run stuff on the command line.


It is all text based and requires the Linux.py class here:

To run these scripts:
1) switch to root
2) download both scripts
3) change Virtualizaiton class to executable
4) run script

#> su -
<enter root password>
#> chmod +x Virtualization.py
#> ./Virtualization.py 

Let me know if you need any further info.

I believe you do so the hypervisor knows about the domain.
You can use the 'create' command this. See virsh help create
